% we can use different (valid LaTeX) syntaxes ...
\metadata{
    \author Fábio Macêdo Mendes
    (...)
}

% ... or ...
\metadata{
    \author{Fábio Macêdo Mendes}
    (...)
}

% ... or even ...
\begin{metadata}
    \author{Fábio Macêdo Mendes}
    (...)
\end{metadata}

% ... or maybe typeset some parts of the quizz explicitly...
\begin{document}
\printlogo
\printheading
\printitem{model}
\printitem{model2}
\printbarcode
\end{document}

% by using a proper syntax (and some TeX wizardry) maybe we can expand 
% \options and \items into the previous code using pure TeX.
